The Guardian is Still Working to Recover From Cyber Incident

Updated on 2023-01-04: The Guardian is Still Working to Recover From Cyber Incident

UK news publication The Guardian is still working to recover from a “serious network disruption” due to what is likely a ransomware attack that began on December 21. Two weeks after the fact, employees are being told to continue to work from home.


  • Traditionally, like satellite ground systems, publishers often relied on air-gap separation between “research” networks like the internet and business critical publishing systems. Too often, even after all the pandemic work at home changes, publishing companies are still relying on isolation that no longer exists. Using NIST IR 8401 as a starting point, block-replacing “satellite ground control segment” with “your name here” would be a decent starting point.
  • Ransomware gangs didn’t take a holiday break, and if anything, are upping their game. Take a pause and make sure that your response plan is still good to go, and as the workforce dynamic of local and home workers continues to evolve, make sure services you planned to rely on during a disruption are still in place, e.g., increased VPN capacity at the height of the pandemic, incorporating any lifecycle activities into your planning.
